I just finished reading The Ice Beneath You by Christian Bale. It is a wartime novel set in Somalia and follows the life of a Private during the war, before the war, and after the war.
I must say that a lot of the story seemed to revolve around the main character trying, and failing, to really come to terms with his purpose in life. In some ways it is a story about how someones life can begin to tumble slowly, and then cascade into an epic downfall. And after reaching rock bottom, the climb back up to a somewhat 'normal' life, was long and difficult.
